To all whom it may concern:

Be it known that I, FRANCIS JosEPH Kunnzr, zen of the United States,residing at Bronxville, New York city, New York, have invented a new anduseful Improvement in Bag-Bottoming Machines, of which the following isa specification.

My invention relates to a bag-bottoming machine.

The objects of this invention areto make a strong and durable bag,having a rigid bottom secured to the tube-like body of the bag, and alsoto produce a machine in which the tube-like body is rapidly and durablybottomed, and in which the bag-body is distend- I ed for assemblage withthe bag-bottom and after assemblage turned inside out prior to theremoval of the assembled bagbody and bag-bottom from the machine.

The objects of the invention are carried out by use of the mechanismillustrated in the accompanying drawings wherein Figure 1 is a top planView of the machine partially in section at line l1 of Fig. 2. This viewshows the I bag-body, bag-bottom and binder in assembling position inthe machine. Fig. 2 is a side elevation of the machine shown in Fig. lbut partially in section at line 2-2 of Fig. 1 through the bag-body,bag-bottom and one of the bag-body clamping members. Fig. 3 is atransverse elevation of the machine, partly in section at line 33 ofFig. 2, looking to the left. Fig. 4 is a sectional elevation taken fromline 44 of Fig. 2,. and shows a mechanism which comprises a loop-presserand a binder-bender mounted thereon; the looppresser engaging the upperside of a link that connects the ends oi the binder and the bender beingin position to bend the out-turned ends of the binder into hookingconnection with the link. This view also shows in section the bag-bodyand bag-bottom. Fig. 5 is a perspective view of the loop-presser andbender mounted thereon. Fig. 6 is a plan of a blank of duck or otherflexible material from which the tube-like bag-body is made. Fig. 7 is adiametric sectional elevation of a suitable form of sheet-metal or otherrigid bag-bottom. Fig. 8 is a side elevation of the binder showing itsends out-turned. Fig. 9 is a transverse sectional view of the binder atline 99 of Fig. 8. Fig. 10 is a perspective view ofthe connecting link,and Fig. 11 shows partially in section and partially in elevation amodified form of the binder-bender.

In the drawings illustrating the best form of my invention now known tome, 1 is a table and 2 and 3 are upright frames oppositely mounted at asuitable distance apart on the upper side of the table and held thereonin any suitable manner, as by bolts 4. Frames 2 and 3 are preferablyconnected by brace rods 5. The distance at which the frames 2 and 3 aremounted a citiapart is dependent on the length of the bag-body that isto be bottomed. The upper end of frame 2 is provided with heads 6 inwhich a horizontal post 7 is rigidly mounted. The upper end of frame 3is provided with bearings 8 in which a horizontal post 9 is mounted,this post being movable endwise in said bearings 8 but not beingrotatable thereon. Posts 7 Y and 9 extend inwardly towards, and are inalinement with, one another. Post 7 is held in the heads 6 convenientlyby transverse bolts 10, or otherwise. The inner end of post 7 isprovided with a bag-bottom clamp-member 11 that is inwardly dished ormade concave on its inner surface. Olamp-member 11 is usually madeannular, peripherally considered, and its outer periphery serves todistend the bottom endportion of the bag-body B when the latter is drawnover the clamp-member for assemblage with the bagbottom B and binder S.Post 9 is provided at its inner end with the other bag-bottomclamp-member 12 which is preferably cut away on its opposite sides 13,13 so that the operator in adjusting the bag-bottom and the bottom endmargin of the bagbody may not be in danger of having his fingers nippedbetween the bag-bottom clamping-members 11 and 12 when the member 12 ismoved towards the member 11 to clamp the bag-bottom firmly in position.

Clamp-member 12 is conveniently provided on its outer face with anintegral sleeve 14 that surrounds post 9. Clamp-member 12 and integralsleeve 14 are made fast on the inner end of post 9 in any suitablemanner, as by a transverse pin 15. Sleeve 14 is provided with a pair ofparallel cars 16 between which the lower end of a hand-lever 17 ispivoted on the transverse pin 18 that passes through the ears and theinner end of lever 17 which is movable from an approximately horizontalposition, as shown in dotted lines in Fig. 1, to a positionapproximately at rightangles to the lengthwise axis of post 9, asindicated by full lines in Figs. 1, 2 and 3. In its approximatelyhorizontal position, lever 171'ests on a suitable support,-in thepresent construction on the adjacent sleeve 21. Lever 17 is providedwith a lateral projection 20 which, when the hand-lever 17 is throwninto its working position, not only holds one end portion of the binderS down on bag-body B, the bottom end margin of which is then assembledwith bag-bottom B, as seen best in Fig. 2, but also engages one of thecorners formed by one of the outward bends of the ends S of the binder.Post 9 is provided, adjacent to stationary sleeve 14, with alocking-sleeve 21, which is formed with a segment-like projection 22that extends away from the sleeve in a direction at right-angles to thelongitudinal axis of post 9 (see Figs. 1, 2 and 3). Projection 22 isprovided on its inner side with parallel ears 23 between which the lowerend of a hand-lever 24 is iulcrumed on a pivot 25 that passes throughthe'ears and inner end of hand-lever 24 which is provided with aprojection 26 that corresponds to projection 20 on hand-lever 17, inthat it holds the other end-portion of the binder S down on the bag-bodyand also engages the other corner formed by the other outward bend ofthe other binder end S. Hand-lever 24 is movable from an approximatelyhorizontal position, as shown by dotted lines in Fig. 1, to a positionat right-angles to the longitudinal axis of post 9. When the handlevers17 and 24 are in inoperative positions shown by dotted lines in Fig. 1,they are, as stated, in approximately horizontal position and theirouter or handle ends extend in the general direction of the outer end ofpost 9. One reason for this position of the handlevers l7 and 24 is thatthey arethen out of the way of the bag-body B when it is turned insideout after it has been assembled with the bag-bottom.

When hand-lever 24 is in its position of rest, indicated by dotted linesin Fig. l, and by full lines in Fig. 3, a projection 27 fast on sleeve21 engages the under side of the head 19 which is a suitable projectionto contact with projection 27 and hold sleeve 2l in a position to keephand-lever 24 in an approximately horizontal position. Another reasonfor having hand.- levers l7 and 24 in approximately horizontal position,when they are not in use, is to enable the operator to readily reach thelevers when he desires to use them, and this he could not convenientlydo if the outer ends of the levers dropped too far downwardly, whenmoved into position of rest or non-use. Post 9 is moved end- Wise toclamp and unclamp bag-bottom B by means of a hand-lever 28, which ispivoted at 2 9 to the base of the machine. The hand lever between itsends is pinned at 30 to the outer end of post 9.

Frame 3 is provided with a projection 31 which is provided with notches32, 32 which receive a locking slide-bar 33 that is mounted on the inneredge of lever 28 and held thereon by guides 34, 34. The upper end ofslide-bar 33 is pivoted at 35 to a hand-piece 36 which in turn ispivoted at 37 to hand-lever 28 so that the handle 39 thereof and thehand-piece 36 can be simultaneously grasped to move post 9 in onedirection or the other and to manipulate slide locking-bar 33 so thatits lower end will slip into one or the other of the notches 32 inprojection 31. A spring 40 is useful in connecting slide locking-bar 33with lever 28 for automatically moving the slide-bar into interlockingposition with one of the recesses 32. When slide lockingbar engages withthe outer recess 32 in projection 31, post 9 and clamp-member 12 arelocked in their position away from clamping-member 11. The connection ofhand-lever 28 and post 9 is such as to prevent rotation of post 9; andwhen the inner end of slide lockingbar 33 engages the inner recess 32 onprojection 31, as shown in Fig. 2, the movable clamp-member 12 is inposition to clamp bag-bottom B securely on the stationary clamp-member11. When the clamp-members are at a distance apart the operator drawsthe mouth of the bag-body B over the periphery of stationary clampmember11 until the bottom end margin of the bagbody is distended at a slightdistance from the lower edge of the bag-body. The rigid bag-bottom B isthen placed in stationary clamp-member 11 with its outer margin incontact with the inner wall of the bag-body which is then supported notonly by the periphery of clamp-member 11 but also by the outer peripheryof the bag-bottom. The operator then moves clampmember 12 into clampingposition and bends the binder S which is preferably rectangular incross-section partially into place on the outer periphery of thebag-body. He then swings hand-lever 17 from its position of rest intoits working position so that the projection 20 engages and holds down onthe bag-body one of the out-turned ends S of the binder or bindingstripS. He then swings hand-lever 24 from its position of rest into positionto engage the other out-turned end S of the binder S (see Fig. 3).Ordinarily the operator will stand on the side of the machine towardswhich hand-lever 17 projects, as shown in Fig. 3, and the operator drawsthe hand-lever 24 towards lever 17 in the direction shown by the arrowin Fig. 3, and from the horizontal position indicated by full linestherein to the final position indicated by dotted lines therein. Thebinder is then strained tightly into place on the outer periphery of thebag-body. Bag-bottom B is provided between its bottom wall and brim withan outwardly projecting shoulder b, and is provided near its brim withan outwardly projecting shoulder b so that there is formed between thesetwo annularly projecting shoulders I) and b, an annular recess b on theouter side of the bag-bottom, the inner edge of which is inclinedinwardly, as indicated by 11 When binder S is strained into andtightened in its position, its out-turned ends S are at a distanceapart, and the bag-body engaged by the binder is forced into the grooveor channel 5 The binder S is preferably rectangular in cross-section, ithaving been found that if the binder be made of round wire, thebag-bottom is apt to be forced out of the bag-body in consequence of thefrequent pushing, by the animal feeding in the bag, against the innerside of the bagbottom. This difficulty is overcome by making the binderrectangular in cross-section.

The edge of the bag-bottom is in-turned at b to prevent the ilexiblebag-body from being cut or frayed at this point, as is the case when theedge of the bag-bottom is not turned inwardly. It has been found inpractice that an animal feeding will very frequently swing the bagsidewise against a wagon-wheel or other object and so cause anout-turned or straight edge of the bag-bottom to fray or ultimately wearthrough the side of the bag-body.

When hand-lever 24 is moved into its final position, indicated by dottedlines in Fig. 3, the segment-like projection 22 of sleeve 21 is carriedpast the outer side of hand-lever 17, as indicated by dotted lines inFig. 3, and so locks hand-lever 17 in its upright or working position.Hand -lever 24 is, of course, kept in its upright or working positionbecause of the fact that the segment-like projection 22 engages itsouter surface above its pivot 25. The out-turned ends S S of the binderare brought, by the movement of projection 26, towards projection 20,and as near together as the length of the binder permits; and, as thehand-levers 17 and 24 are now in radially operating position as shown inFig. 3, the operators hands are free to place the connecting link L overthe projecting ends S S. When the link L is thus applied, the operatorswings handlever 50 from its horizontal position of rest,' as indicatedby full lines in Fig. 2, into its working position as indicated bydotted lines in Fig. 2. Lever is pivoted at 51 on a stud 52 which isconveniently socketed in a recess in the post 9 and held therein by theset-screw 19, above mentioned. Hand-lever 50 carries a link-presser 52which, in the construction shown, is conveniently provided with cars 53,53 that are bolted at 54 to the hand-lever. When lever 50 is swung intooperating position, the link-presser 52 moves between the out-turnedends S, S, as indicated in Fig. 4, and is then in position to push thelink L home. Opposite sides of hand-lever 50 (Fig. 5) are recessed at55, 55 so that the lengthwise central slot 56 of the forked presser 57is mounted on lever 50 in such wise as to be slid over the presser 52carried by the hand-lever. The inner ends of forked presser 57 arebeveled or otherwise shaped at 58 in such wise as to engage theout-turned ends S, S and bend them downwardly over the loop so that theloop and the ends of the bender are permanently connected together.Bender 57 is conveniently provided with a head 59 between the under sideof which and the upper side ofhand-lever 50 a spring 60 is interposed.When bender 57 is forced inwardly to bend the ends of the binder overthe ends of link L, spring 60 is compressed and the spring serves toretract the bender. The outward movement of the bender is limited bycontact of the lug 61 on the bender with a pin 62 on hand-lever 50, asshown in Fig. 2.

Bag-body B is preferably made from a blank of duck or the like such asshown in Fig. 6, the opposite ends of the blank being stitched together,so that a tube-like bag-body is produced. One long side of the blank,corresponding to the bottom end of the bag, is shorter than the oppositelong side of the blank, corresponding to the mouth of the bag.Consequently, bag-body B has an enlarged open end into which an animalmay thrust its head for feeding in the lower part of the bag, the bottomof which is preferably perforated at any suitable places as at y, forventilating the bag. The bag-body is also preferably provided withsuitably disposed ventilating holes y. The under side of the bag-bottomis preferably provided with annular projections z, z, to keep theperforated bottom surfaces of the bagbottom out of direct contact withthe ground.

I i l I In Fig. 11, showing a slight modification, wherein theconfiguration of the inner end of the presser 57 is such that itsengagement with the out-turned ends S, S will completely turn and clenchthe out-turned ends on link L. When the bevel construction shown in theother figures is used, it is frequently desirable to manually hammer theout-turned ends into their final clenching position with reference tothe link L.

Various changes may be made in the construction illustrated withoutdeparture from my invention.

The hand-lever 50 is so arranged that when it is in its position of restor non-use, it will be out of the way of the bag-body when the latter isturned to bring its wall over the outer side of the binder so as toconceal the same and thicken and strengthen the bag around its lower endcorner.

What I claim is 1. In a bagbottoming machine, the combination of abag-bottom clamp comprising separable members one of which is movablefrom and towards the other; means for actuating the movable clamp-memberand means for tightening a binder in a path encircling the periphery ofthe bag-bottom clamp.

2. In a bagbottoming machine, the combination of a bag-bottoming clampcomprising separable members one of which is movable from and towardsthe other; means for actuating the -movable clamp-member; means fortightening a binder in a path encircling the periphery of the bag-bottomclamp; and means for bending the ends of the binder into interlockingconnection with a link which unites said ends.

3. In a bag-bottoming machine, the combination of a bag-bottom clampcomprising separable members one of which is movable from and towardsthe other; means for actuating the movable clamping member; means fortightening a binder in a path encircling the bag-bottom clamp; means forbending the ends of the binder into interlocking connection with a linkwhich unites said ends; a binder-tightening mechanism comprising a pairof levers each provided with a binder-engaging projection and movablefrom a position of rest to a working position; and a hand-lever movablefrom a position of rest, which position is such as to permit thebag-body to be turned inside out while in the machine, into its workingposition and carrying a linkpresser and a bender.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing wit nesses, this 13th day of June, 1906.
